‘kRepsOverA’ returns a filter function with bindings for ‘k’ and ‘A’. This function evalutes ‘TRUE’ is at least ‘k’ of the means of the replicates are larger than ‘A’.

1	kRepsOverA(k, A = 100, INDEX)

`k`	The number of sets of replicates with mean greater than A.
`A`	The value to exceed.
`INDEX`	List of factors, each of the same length as the input vector.

A function with bindings for ‘A’, ‘k’, and ‘INDEX’.
